Description

Why escape space? It is the same in my tests.
In addition, Replace [0-9] with \d, which I think is more beautiful😄 and can reduce the file size a little bit.
Maybe a little bit more performance? I'm not sure.

Refactoring is fine but there is always a certain amount of risk for breakage. I hope you are really confident about these regex changes...

Maybe a little bit more performance?

I don't think that matters at this place.

I'm very confident about the substitution of [0-9] to \d.

\d: Matches any digit (Arabic numeral). Equivalent to [0-9]. For example, /\d/ or /[0-9]/ matches "2" in "B2 is the suite number".

Regarding the escape of spaces, is this the case?

Note that some characters like :, -, @, etc. neither have a special meaning when escaped nor when unescaped. Escape sequences like :, -, @ will be equivalent to their literal, unescaped character equivalents in regular expressions.

I did not find any results related to the escape of spaces after searching. I think it should belong to the above situation.
Therefore, with the successful results of auto-checks, I think they are the same.
